Learning from a Disastrous Megathrust Earthquake

open access: yesEos, 2021
Ten years of interdisciplinary studies since the disastrous Tohoku-oki earthquake have improved our knowledge of earthquake-cycle processes and hazard, but prediction of such events remains elusive.

Evolution of Scaled Energy During Earthquake Ruptures

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Earthquake ruptures radiate seismic energy in complex ways, reflecting the interplay of fault heterogeneity and rupture dynamics. How the radiated energy evolves during rupture, and whether this evolution varies systematically with earthquake properties, remains poorly understood. Here we analyze more than 1,500 global earthquakes using moment‐

Dimensionality Reduction Techniques for Analyzing Tsunami Simulations in Hazard Assessment and Forecasting Applications

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract A wide selection of linear and non‐linear dimensionality reduction techniques is evaluated on synthetic tsunami data that is the basis for tsunami hazard assessment and computational forecasting. The data were computed from earthquake rupture forecasts (ERFs) supplying initial generation conditions and a linear long‐wave Green's function ...

A Multi‐Region Deep Learning Framework for Low‐Frequency Earthquake Detection: Application to the Guerrero Seismic Gap

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Low‐frequency earthquakes (LFEs) provide key constraints on slow earthquake processes but remain difficult to detect because of their low signal‐to‐noise ratios (SNR) and emergent onsets, particularly in offshore environments where seismic networks are sparse.

Interseismic Coupling and Slow Slip Events on the Cascadia Megathrust

open access: yes, 2019
In this study, we model geodetic strain accumulation along the Cascadia subduction zone between 2007.0 and 2017.632 using position time series from 352 continuous GPS stations.

Linking 3D Long‐Term Slow‐Slip Cycle Models With Rupture Dynamics: The Nucleation of the 2014 Mw 7.3 Guerrero, Mexico Earthquake

open access: yesAGU Advances
Slow slip events (SSEs) have been observed in spatial and temporal proximity to megathrust earthquakes in various subduction zones, including the 2014 Mw 7.3 Guerrero, Mexico earthquake which was preceded by a Mw 7.6 SSE.

Spatial changes in inclusion band spacing as an indicator of temporal changes in slow slip and tremor recurrence intervals

open access: yesEarth, Planets and Space, 2021
Slow slip and tremor (SST) downdip of the seismogenic zones may trigger megathrust earthquakes by frequently transferring stress to seismogenic zones.

Quantifying the Role of 3D Fault Geometry Complexities on Slow and Fast Earthquakes

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Traditional models of slow slip events (SSEs) oversimplify fault geometry, although imaging shows subduction faults are segmented and complex. We examine how fault interactions control slip behavior using 3D quasi‐dynamic simulations of two parallel faults with uniform rate‐weakening friction accelerated by hierarchical matrices.

Asthenosphere Flow Modulated by Megathrust Earthquake Cycles [PDF]

open access: yesGeophysical Research Letters, 2018
Abstract Subduction megathrusts develop the largest earthquakes, often close to large population centers. Understanding the dynamics of deformation at subduction zones is therefore important to better assess seismic hazards. Here I develop consistent earthquake cycle simulations that incorporate localized and distributed deformation ...

Fault Slip Reversals Preceded the Intraplate 2021 Earthquake Series in the Vienna Basin (Central Europe)

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...
